A PRELIMINARY ANALYSIS OF GRAVITY VARIATION IN CANGZHOU REGION OF HEBEI PROVINCE

The data of gravity repetition measurement show a tetidency variation in Cangzhou region, with its maximum amplitude reaching 92×10^-8m/s² The analysis results in this paper has considered that such a variation is partially related with the ground subsidence in Cangzhou region, partially related with det-p crustal variation factor,and cannot rule out the occurrence possibility of a moderately strong earthquake.
